1 Claim. (Cl. 214-1) The present invention relates to new and usefulimprovements in hoists for boats to lift and store small boats from thewater.

An important object of the invention is to provide a boat hoist adaptedfor installing on docks to lift outboard or rowboats from the water andto support the same on its side in order that the boat cannot becomefilled with water, when not in use.

Another object of the invention is to provide a hoist of this characterof simple and practical construction, which is strong and durable,relatively inexpensive to manufacture, which may be operated by a singleperson, and which is otherwise well adapted for the purpose for whichthe same is intended.

These together with other objects and advantages which will becomesubsequently apparent reside in the details of construction andoperation as more fully hereinafter described and claimed, referencebeing had to the accompanying drawings forming a part hereof, whereinlike nlnnerals refer to like parts throughout, and in which:

Figure 1 is a front elevational view;

Figure 2 is a side elevational View; and

Figure 3 is a side elevational view showing the hoist after lifting theboat from the water.

Referring now to the drawing in detail, wherein for the purpose ofillustration, I have disclosed a preferred embodiment of the invention,the numerals 5 and 6 designate a pair of posts which are suitablysecured in upright, spaced apart relation with respect to each other tothe outer edge of a wharf or dock 7. Uprights 8 and 9 are secured to theouter surface of the poles 5 and 6 by bolts or the like 10 to supportthe uprights in a position extending upwardly above the upper ends ofthe posts.

Slings 11 and 12 which are preferably constructed of straps of buoyantplastic or other suitable flexible material are attached at one endportion in slots 13 at the lower end portions of the uprights 8 and 9 byat least one of the bolts 10. Cables 14 and 15 are attached,respectively, to the other ends of the slings 11 and 12.

A winch 16 is attached in brackets 17 at the upper portion of theupright 8 and is operated by a crank handle 18 and cable 14 extendsdirectly from the sling 11 to the winch. Cable 15 extends upwardly fromsling 12 Patented Apr. 8, 1958 over an upper pulley 19 suitably securedat the upper end portion of upright 9 and then, downwardly from theupper pulley 19 under a lower pulley 20 and from which the cable 15extends under a pulley 21 which is suitably secured to the other upright8. The cable 15 then extends upwardly from the pulley 21 to the winch 16so that both cables 14 and 15 are simultaneously and uniformly wound onthe winch.

In the operation of the device, the slings 11 and 12 are lowered intothe water so that the same may be floated or otherwise placed under aboat 22. The cables 14 and 15 are then pulled upwardly by the Winch 16whereupon the boat will be lifted from the water and turned on its sideand supported in that position by the slings 11 and 12 in an elevatedposition above the water, as shown in Figure 3 of the drawing.

Resilient pads 23 are suitably secured to the outer surface of theuprights 8 and 9 and against which the uppermost portion of the boatrests to prevent marring the finish of the boat.

From the foregoing, the construction and operation of the device will bereadily understood and further explanation is believed to beunnecessary. However, since numerous modifications and changes willreadily occur to those skilled in the art, it is not desired to limitthe invention to the exact construction shown and described, andaccordingly, all suitable modifications and equivalents may be resortedto, falling within the scope of the appended claim.

What is claimed as new is as follows:

A boat hoist comprising a winch attached in an elevated position to asupporting structure, a pair of flexible straps attached at one end tothe structure below the winch in spaced relation to each other, and apair of cables attached to the other ends of the straps and extendingupwardly therefrom in spaced parallel relation to each other andconnected to the winch for winding thereon, said straps being adapted toextend transversely under a boat for raising and turning the boat on itsside against the supporting structure, said straps being constructed ofbuoyant material and being detachable from said cables for floating intoa transverse position under the boat, said winch being positioned in avertical plane with one of the straps to extend one of the cablesdirectly upwardly from said one strap to the winch, and pulleys on thesupporting structure to guide the other of said cables directly upwardlyfrom its connected strap and thence horizontally to the winch.
